The cup holder body 122 is used for winding the cup tape 10 to which the test cup is attached, and the cup holder body 122 is restricted to the mounting shaft 1211 by the combined action of the pretensioning unit 1213 and the locking buckle 1212.
Further, the mounting assembly 121 further includes an elastic locking unit 1214, the mounting shaft 1211 is provided with a mounting hole 1211a penetrating through a first end of the mounting shaft 1211, the elastic locking unit 1214 is disposed in the mounting hole 1211a, the locking buckle 1212 is located at the first end of the mounting shaft 1211 and is rotatably connected to the mounting shaft 1211, and the locking buckle 1212 abuts against the elastic locking unit 1214. Wherein the locking buckle 1212 is operable to rotate and disengage from the cupholder body 122 to enable the cupholder body 122 to be removed from the first end of the mounting shaft 1211.
In the above-mentioned cup tray mechanism 120, when the lock catch 1212 abuts against the cup tray main body 122, the elastic lock catch 1214 can abut against the lock catch 1212, preventing the lock catch 1212 from rotating and separating from the cup tray main body 122 when no external force is applied or the applied external force is small, and preventing the cup tray main body 122 from slipping out of the first end of the mounting shaft 1211. When it is desired to remove the cupholder body 122 from the mounting shaft 1211, the locking buckle 1212 may be operated to rotate to disengage the locking buckle 1212 from the cupholder body 122, thereby enabling the cupholder body 122 to be removed from the first end of the mounting shaft 1211. When the cup tray mechanism 120 needs to take out the cup tray main body 122, only the locking buckle 1212 needs to be rotated, and the operation is convenient.
In one embodiment, the locking buckle 1212 includes a first positioning wall 12121 and a second positioning wall 12122 connected to the first positioning wall 12121, the first positioning wall 12121 and the second positioning wall 12122 are disposed at an angle, and the locking buckle 1212 is operable to rotate so that a portion of the locking buckle 1212 abutting the elastic locking unit 1214 switches between the first positioning wall 12121 and the second positioning wall 12122; wherein, in the case that the first positioning wall 12121 abuts against the elastic locking unit 1214, the second side of the cup tray main body 122 abuts against the locking buckle 1212; with the second positioning wall 12122 against the elastic catch unit 1214, the locking buckle 1212 is separated from the cup tray body 122, and the cup tray body 122 can be taken out from the first end of the mounting shaft 1211.

As shown in fig. 5, an embodiment further relates to a method for early warning of a cup-tray system, where the method for early warning of a cup-tray system is applied to the cup-tray system as described above;
The early warning method of the cup and disc system comprises the following steps:
s100, acquiring a current value of the motor 151;
Specifically, the motor 151 is a stepper motor 151 with feedback current, and a current signal sensor is built in. In the operation of the cup and tray apparatus 100, as the test cups on the cup and tray mechanism 120 are used less, the track of the cup belt connected between the cup and tray main body 120 and the first tension wheel 131 closest to the cup and tray main body 120 is offset along the arrow direction to generate an offset included angle α, the larger the included angle α is, the higher the angular rotation speed of the cup and tray is, the larger the required output torque of the stepper motor 151 is, the larger the output torque is, the larger the signal quantity of the current signal sensor is, and the signal detected by the current signal sensor can be transmitted to the control board 500.
And S200, sending out an early warning signal when the current value of the motor 151 is larger than a preset value.
Specifically, as the included angle α is larger, the angular rotation speed of the cup disc is higher, the required output torque of the stepper motor 151 is larger, the signal quantity of the current signal sensor is larger, that is, when α is 0 (when the cup belt 10 is in the initial state), the current value of the motor 151 is I 1, the current value of the motor 151 is that the difference between I 2,I2 and I 1 and the angle α has a linear relationship, when α reaches the limit value, the current value is an early warning time, and an early warning signal is sent at this time, so that an operator prepares to replace the cup disc main body 122, wherein after the early warning signal is sent, the residual test cup storage quantity on the cup disc mechanism 120 can also be tested for 20-30 tests.
The early warning signal can be in the form of a flashing lamp or in the form of early warning sound.
Referring to fig. 4 and 6, in particular to the present embodiment, when the locking buckle 1212 abuts against the disk main body 122, the pretensioner 12132 applies a pretensioning force to the abutting body 12131, at this time, the disk main body 122 and the abutting body 12131 cooperate to form a whole that does not rotate relatively, and the pretensioner 12132 also limits the rotation of the whole relative to the mounting shaft 1211, and makes the whole generate a rotation limiting moment T 1,T1, so that the greater the pretensioning degree of the pretensioner 12132, the greater T 1. The test cup on the cup belt 10 and the test cup thereon are affected by the gravity of the earth, so that the whole formed by the combination of the cup tray main body 122 and the supporting body 12131 generates a rotation moment T 2 relative to the mounting shaft 1211, and the pre-tightening effect of the cup tray main body 122 can be achieved when T 1 is larger than T 2.
The relationship between the difference between I 2 and I 1 and alpha is as follows:
I2-I1＝y(T1-T2)+xα；
Wherein, I 1 is the current of the motor 151 when alpha is 0; i 2 is the present current of the motor 151; t 1 is the moment generated by the pretensioner 12132 on the whole formed by the cooperation of the cup main body 122 and the supporting body 12131; t 2 is the moment generated by the cup belt 10 and the test cup on the cup belt 10 on the whole formed by the cooperation of the cup tray main body 122 and the supporting body 12131 due to the influence of gravity, and satisfies that T 1 is larger than T 2; y is a torque-current conversion constant and is a fixed value in the device; x is an angle-current conversion constant and is a fixed value in the device;
Therefore, according to the formula, the alpha can be judged by calibrating the difference between I 2 and I 1, and when I 2 reaches a preset value, the alpha can be indicated to reach a limit value, so that the test cup can be early warned about to run out.
The preset value of the current of the motor 151 may be reversely derived according to α, specifically, in the actual operation process, when the remaining test cup reserves on the cup and disc mechanism 120 can be tested for 20-30 tests, the value of α may be measured or calculated, and the value of I 2 may be obtained, so the value of I 2 may be recorded as the preset value.
By using the early warning method of the cup and disc system, an early warning signal can be sent when the test cup is about to run out, so that an operator can replace the cup and disc main body in time, unexpected accidents are avoided, and the safety is improved.
An embodiment also relates to a coagulation device comprising a cup and tray system as described above, and an early warning method of the cup and tray system as described above is applied.
The cup and tray system is applied to coagulation equipment and is used for providing and conveying test cups. In the cup system, two cup devices 100 are symmetrically arranged left and right, any one cup device 100 can be independently operated, and any one cup device 100 can be independently disassembled. Thus, when one of the cup tray apparatuses 100 is subjected to operations such as maintenance, replacement, loading of a new test cup, and the like, the other cup tray apparatus 100 can also be operated normally, so that the coagulation device can achieve the purpose of non-stop testing, thereby improving the test efficiency.
